they're ****. Just a set of $10 headphones with an extra twenty cents worth
of foam on each side. The impressive part about bose company is that they
sell them for hundreds of dollars. There's one born every minute.

You're saying that they sell noise-cancelling headphones that don't actually
contain any form of active noise cancellation?

Active noise cancellation is rubbish too. I bought a set, and while they
did reduce the background "throbbing" noise from the engines slightly,
they don't have any effect on "random" noises like people talking or
announcements (the latter a particular problem on some trains, rather
than planes).
